Parrotman,
Interesting Handle... I went from trainers to a Spitfire. The eliptical wing is more forgiving. However, once you get the hang of it, none are impossible. The first take off tells you a lot about a model. My first Spitfire take off was a bit wobbly, but controlable. The key is to keep thinking ahead of the airplane and don't panic. My 15 year old is moving from his Avistar, (which he flies like a fighter plane) to a Great Planes P-51. He's going to a scratch built scale Spitfire I have built for him after that. My oldest son went from an Eagle II trainer to a Dynaflite P-51 and then a T/F P-40. He now flies full scale F-16's for the USAF! He still ocassionally flies his T/F P-40 when he has the time.

In short, you are the only one who can say when you are ready to advance. Get the Great Planes G2 Flight Simulator and practice until you can fly any airplane on the program with confidence. You'll be amazed at how much more a better pilot you'll be and how much money you'll save in crashes. I use mine regularly, and I fly with other guys on line. It's a BLAST!
Good luck.

"Keep 'Em Flying!"
